Calgary's most lucrative postal code during the 2022-23 fiscal year was the 'T2P' postal code, which is located in Downtown Calgary.
The largest of these was a $32.2 million contract awarded to "Eagle Professional Resources" by Shared Services Canada for "Human resources management services", which can be found here: Link
